If at first you don't succeed...Wiz Khalifa throws son Sebastian another birthday party and 'this time Amber Rose lets him go'

Wiz Khalifa threw his son another party after his ex Amber Rose allegedly refused to let the boy attend the first bash.

The rapper instagrammed pictures of him having a ball with little Sebastian - who turned two years old - one week after his failed first attempt.

'I'll give you the world and everything in it. #BirthdayBash #TaylorGangPartyDontStop,' he wrote, sharing pictures and a video of the newly-two-year-old playing with his pressies.

Happy second birthday! Wiz Khalifa finally got to throw his son a birthday party on Friday with the birthday boy present this time

Last week the 27-year-old posted much sadder pictures of the pirate-themed party he threw for his boy, including balloons, banners, a table full of presents and a Jake And The Never Land Pirates cake... but no Sebastian.

Amber was supposed to drop Bash off at the party so everyone could celebrate his second birthday as parents, but that never happened,TMZ reported

Wiz was allegedly heartbroken the little boy could not ring in the day with civil parents and all the guests who showed up.

'Only thing missing was Bash,' he wrote then, claiming the boy's mother had prevented him from coming just to get back at his dad. ‘Let’s all cut this for my boogie boo,' he begged.

The two are embroiled in a bitter and rather public custody battle over their only child, frequently hitting out at each other via social media.

Although this time round, Wiz took the high road and didn't mention the model's name, opting instead to just enjoy his share of time with the boy.

Amber meanwhile couldn't help but take another dig at the Black And Yellow rapper, tweeting on the same day: 'I'm keeping my sons pictures off of social media from now on. He doesn't have to be in the middle of these messy fake stories.'

This came after the 31-year-old model had spent Sebastian's actual birthday with him, posting several Instagram pictures and videos of the two sharing the day.

Wiz spent the rest of that day poring out to his 18million Twitter followers: 'ive never voiced my true unhappiness out of fear of the person I was with and what she would do to make me more unhappy of anyone knew’ he tweeted.

Wiz and Amber married in July 2013 but split in September 2014. She claims he cheated, which he continues to deny.

Meanwhile Amber's other Twitter battlefront against the Kardashians and her other ex boyfriend Kanye West seems to have calmed down over the last few days.
